Dousing Flames with Low-Frequency Sound Waves

A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive method of fire control, which could find applications in fighting small fires in the home, and the researchers now hold a preliminary patent application for their device.

While the concept of using sound waves to extinguish flames is not new, previous attempts to realize the principle – including efforts by teams at West Georgia University and the US Defense Advanced Research Projects Agency (DARPA) – had not been successful.

Undeterred by this, as well as initial [...]

Precision Nanobatteries by The Billions

Tiny batteries formed inside nanopores demonstrate that properly scaled nanostructures can use the full theoretical capacity of the charge storage material. These nanobatteries delivered their stored energy efficiently at high power (fast charge and discharge) and for extended cycling.

Precise structures can be constructed to assess the fundamentals of ion and electron transport in nanostructures for energy storage and to test the limits of three-dimensional nanobattery technologies.

Nanostructured batteries, when properly designed and built, offer promise for delivering their energy at much higher power and longer [...]

High Speed Emergency Network with Drones

Each year nearly a million people in Europe suffer from a cardiac arrest. A mere 8% survives due to slow response times of emergency services. The ambulance-drone is capable of saving lives with an integrated defibrillator. The goal is to improve existing emergency infrastructure with a network of drones. This new type of drones can go over 100 km/h and reaches its destination within 1 minute, which increases chance of survival from 8% to 80%! This drone folds up and becomes a toolbox for all kind of emergency supplies. Future implementations will also serve other use cases such as drowning, diabetes, respiratory issues and traumas.

Seeking The Great White Whales Of Personal Health Devices

Personal health-measuring devices — wearable digital trackers for weight, blood pressure, calories, and daily activity — generate a lot of buzz in the press.  But for all the hype, most of these items soon will join other “cool” technologies that had sought but never quite found the true unmet customer need.  These “vital” statistics turn out to be not that vital after all.

So, are there any medical needs where personal health devices can make a major difference in people’s lives — real needs currently going unfilled or only partly filled?  According to Tim Bernstein, Chief Operating Officer of yet2, a firm that helps businesses find and acquire new technologies, “Right now we [...]

The Health Concerns in Wearable Tech

In 1946, a new advertising campaign appeared in magazines with a picture of a doctor in a lab coat holding a cigarette and the slogan, “More doctors smoke Camels than any other cigarette.” No, this wasn’t a spoof. Back then, doctors were not aware that smoking could cause cancer, heart disease and lung disease.In a similar vein, some researchers and consumers are now asking whether wearable computers will be considered harmful in several decades’ time.We have long suspected that cellphones, which give off low levels of radiation, could lead to brain tumors, cancer, disturbed blood rhythms and other health problems if held too close to the body for extended periods.Yet here we are [...]

Cyberlegs Project Wants to Equip Amputees with Robotic Limbs

You'll see a lot more instances of robotic arms in the news, but it doesn't mean high-tech prostheses for the lower limbs don't exist. The Cyberlegs proj

This 3D Printed Exo-Prosthetic leg Is A Work Of Art

3D printing has transformed the prosthesis into something that can be readily created, accessible and comes at a very low cost production. However, so far the mix has been missing the aesthetics. The Exo-Prosthetic Leg will be changing it by offering something that is different and far more aesthetically pleasing when compared with the robotics prosthesis. The limb is also quite cheap in cost.

It makes use of 3D scanning, modeling and printing technology to manufacture an exoskeleton that is customizable and is made of titanium. It is created in such a way that it is capable of being the exact form replica of the amputated limb. There are more than 2 million amputees in the US [...]
